Time-of-check Time-of-use (TOCTOU) Race Condition in shadow - CVE-2013-4235

Vulnerability identifier: #VU59131

CSH Severity: Low

CVSS v4: 5.7 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N]

CVE-ID: CVE-2013-4235

CWE-ID: CWE-367

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local user to delete or modify arbitrary files on the system.

The vulnerability exists due to a race condition in shadow-utils when executing usermod/userdel operations. A local user with write access to the directory that is being moved or deleted by the usermod/userdel commands can modify or delete arbitrary files on the system.

Successful exploitation of the vulnerability may allow an attacker to corrupt arbitrary files on the system and perform a denial of service (DoS) attack.
